there is a direct stock replacement K&N filter, similar to
the UNI.
I have had both and find the K&N easier to clean and re-oil.

to access the airbox where the AI tube was connected you
need to remove the left side cover ( chrome cheese grater ,
and plastic cover ).
remove the screw from the bottom of the chrome cover, then
the 2 screws the hold the plastic cover on.
pull the cover off .
on top of the airbox at the forward edge is a hole where
the tube for the AI was , should be plugged.
